5 Disconnecting the Inverter from Voltage Sources
13.
Danger to life due to electric shock when touching exposed DC
conductors or DC plug contacts if the DC connectors are damaged or
loose
The DC connectors can break or become damaged, become free of the DC cables, or no
longer be connected correctly if the DC connectors are released and disconnected
incorrectly. This can result in the DC conductors or DC plug contacts being exposed.
Touching live DC conductors or DC plug connectors will result in death or serious injury due
to electric shock.
• Wear insulated gloves and use insulated tools when working on the DC connectors.
• Ensure that the DC connectors are in perfect condition and that none of the DC
conductors or DC plug contacts are exposed.
• Carefully release and remove the DC connectors as described in the following.
14. Release and remove the DC connectors. To do so,
insert a flat-blade screwdriver or an angled
screwdriver (blade width: 3.5 mm) into one of the
side slots and pull the DC connectors out. When
doing so, do not lever the DC connectors out, but
insert the tool into one of the side slots only to
release the locking mechanism, and do not pull on
the cable.
15. Ensure that no voltage is present at the DC inputs of the inverter.
16. Use an appropriate measuring device to ensure that
no voltage is present at the AC terminal block
between L1 and N, L2 and N, and L3 and N.
Insert the test probe of the multimeter into the round
opening in the terminal.
17. Use an appropriate measuring device to ensure that no voltage is present at the AC terminal
block between L1 and PE, L2 and PE, and L3 and PE. Insert the test probe into each round
opening of the terminal.
18. Ensure that no voltage is present between any terminal of the multifunction relay and PE of the
AC terminal block.
